Huddersfield Town boss David Wagner celebrates his first anniversary as Town's head coach today, with the German appointed on November 9, 2015.

The Terriers have not looked back since that day, and have gone on to achieve record-breaking success with the former Borussia Dortmund II man this campaign.

Wagner masterminded Town's best start to a season and sees his side sat in third place in the Championship, pressing Newcastle and Brighton who currently fill the automatic promotion spaces.

Town's performances - and results - have surprised many pundits this season, but what may also come as a surprise is that Wagner is now one of the longest serving managers in the second tier of English football.

Only six bosses have been in their current positions for a longer time than Wagner, with Ipswich manager Mick McCarthy leading the pack with over four years at Portman Road under his belt.

Former Town man Simon Grayson and Gary Rowett round out the top three with three and two years in their current tenures repectively.

Chris Hughton and Alex Neil are both closing in on their second anniversaries at Brighton and Norwich, with Sheffield Wednesday manager Carlos Carvalhal five months ahead of Wagner.
